Plates are Black Oxide coated.
Our Heavy Duty Shell Plates for the Dillon Super 1050 start out as S-7 tool steel and are then through hardened, not case hardened. The pocket dimensions and location are different from the stock Dillon plate, allowing better adjustment, reliable feeding, and less flexing of the shell plate.
Installation: Please see the video below for proper setup. Do NOT use the Dillon instructions. Failure to setup per the video, and failure to keep the press clean under the shell plate will result in premature failure due to fatigue stress.
Note: Tuning of the extractor tab will be required if rough extraction occurs. For instructions on tuning, click HERE.
